a long time ago maybe 10 years ago I used to play a game online that looked like a variant of qix. The player looked like a less than sign and you tried to gain a certain percentage of the board by enclosing areas like in qix. What differs in this variant is that the enemy was what looked like little flies flying around. The game had levels and each level would add another "fly". I can not remember what the game was called but I think it started with an "f" and was on a fairly popular flash gaming website.
